After dissolving compound 6a (2.00 g, 7.54 mmol) in MC (10 ml) and anhydrous DMF (10 ml), oxalyl chloride (1.90 g, 15.0 mmoL) was added thereto and the agitation for 30 minutes was carried out. After the identification of the reaction progress with TLC, the reaction was terminated. Then, three times extractions were carried out with EA and three times washings were carried out with brine. Water was removed by using Na2SO4, solvents were removed and then, the column chromatography was carried out with EA/HX ( 1/9). As the result, Compound 7a was obtained.
